Drinking water systems
Hygiene
Grundfos pressure booster systems are functionally
tested by running water through the system. During
the test, Grundfos continuously surveys the quality of
the test water. Since it is not possible to completely
drain and dry the system after the test, the system
must be rinsed or flushed thoroughly before being
taken into use in a drinking water sector due to risk of
bacteria growth. This also applies if the system has
been shut down for a long period of time. Rinsing and
flushing must always be done in accordance with
local regulations.
Contaminated drinking water endangers health.
